Title: Signal tracking,estimation,and removal processes using a maximum,a posteriori algorithm, and sequential signal detection
Inventor: BORRELL RONALD A
IPC: G01S7/52
Filed: 1993-03-11
Abstract: A system and method for automating signal tracking, estimation of signal parameters, and extraction of signals from sonar data to detect weaker signals. A maximum a posteriori (MAP) algorithm processing provides a track output of the signal which is used as a guide or template to provide optimal spectral integration on an unstable or frequency varying line. The present invention includes track integration 15, parameter estimation 17, signal track normalization 16A, and sequential signal detection 18. The present invention partitions 12 the input band into frequency subwindows (31-35 Fig 2, not shown). For each subwindow, the strongest signal is tracked, its parameters are estimated, and then the signal is normalized (removed) 17 from the subwindow. This is repeated until the entire subwindow set is processed. Then the subwindows, now with their strongest signals removed, are recombined to form one input band. This aggregated procedure represents one processing pass. In the next pass, the entire above procedure is repeated with either the same or new subwindow boundaries. This continues until a predetermined number of passes is completed. Sequential signal detection is provided from one data frame to the next, a problem that is beyond the capability of conventional systems and methods for tracking frequency lines of unknown frequency modulation and amplitude. <IMAGE>

Title: Capacitive differential pressure detector
Inventor: TAMAI MITSURA
IPC: G01L13/06
Filed: 1993-07-20
Abstract: A capacitive differential pressure transducer (Fig. 3) includes a diaphragm (10) mounted between two fixed electrodes (15 and 20). The assembly is mounted in a housing as in Fig. 4, with pressures P1 and P2 being introduced via passages (57 and 73), and central openings (25 and 26) in the fixed electrodes. To obviate non-linearity being introduced by deformation of the fixed electrode (15) by a very high pressure P2, the electrode is mounted on a substrate (80) and spaced therefrom by a bonding portion (42). The substrate (80) can thus be deflected by P2 acting on its outer face, without affecting the electrode (15) since the latter is subject on both sides only to the pressure P1. <IMAGE>

Filed: 1994-04-05
Abstract: The rangefinder includes an optical scanner and a laser 10. The optical scanner comprises a rotating disc 20 with a circular array of concave reflectors 18 thereon. Mirrors direct light from the light source towards the concave reflectors 18 on the scan disc end thence towards a target. Light received from the target is directed towards the concave reflectors 18 on the scan disc 20 by mirrors along a plurality of spaced channels. Detector arrays (40a, 40b, Fig 4), one for each channel, receive light reflected from a respective concave reflector; a comparison of the positions at which the light impinges gives the objects range. Scanning allows a 3-dimensional picture to be built up. The main application is to vehicular collision avoidance. Alternatively, the detector outputs may be fed to two displays, one for each eye of an operator, to give a stereoscopic effect. Alternatively, the outputs may be used for traffic control, eg at traffic lights, and to record infringements. Application to robots is also possible. <IMAGE>

Title: System for fuel-injecting a diesel engine with a first fuel and a second fuel, eg an emulsion
Inventor: SCHOENFELD DIETER
IPC: F02M63/00
Filed: 1996-09-20
Abstract: The injection nozzle 1 is supplied with a first fuel by a high-pressure pump 3 via a preaccumulator 2 and path DA of solenoid valve 4. The engine can also be operated with a second fuel in the form of pure fuel or an emulsion of fuel and another substance, eg water, which is insoluble with respect to the fuel. The second fuel is directed in a circuit through the inner volume V of the injection nozzle 1 and the duct AB by a pump 9 with means 10 for admixing water which is connected to line EF from which a line 12 leads to the injector volume V via a non-return valve 7. Between injections, path AD of valve 7 is opened so that the volume V is filled with the second fuel; at the start of injection, valve 7 is switched to path AC so that the second fuel is injected into the engine upon actuation of the injection nozzle by the first fuel. To operate with pure fuel, either pump 9 or the water supply 10 can be shut down. The mixture ratio of the fuel and of the other substance in the 15 second fuel is adjusted in the circuit. The advantages are more reliable restarting after lengthy interruption in operation and low wear of the injection system.
